LambdaRogue is a rogue-like role playing game set in the future of a somehow "parallel world" to our own.

People had to go underground to survive a war between human society and the once peaceful Drakh'Nar, another species on the planet. People founded the NeoTerr nation and tried to build up a prosperous civilization.

This worked, until suddenly strange creatures came down the Great River Styx. The river has now become a source of fear and terror. The player has to follow the river through NeoTerr and discover the reason. The atmosphere is rather strange, influenced by fantasy and cyberpunk.
